Ah it looks like you are correct. It used the NAPI. Per wikipedia: > In November 2013, citing the planned deprecation of NPAPI browser plug-ins by major browsers, Quake Live began to phase out its browser version and began migrating to a standalone client. However, this change necessitated the removal of OS X and Linux support from the game. https://en.wikipedia.org/wiki/Quake_Live https://en.wikipedia.org/wiki/Quake_Live Now I remember why I stopped playing as I only had a macbook at the time.
